Abstract

A method for managing defective storage region of optical disc includes recording information of prompting whether relevant sectors in each sector unit of spare block can be used to carry out normal replacement or not when data to be stored in defective block is replaced to be stored in spare block, storing said information as defect management information in DMA then recording identification information used to identify whether storage defect is existed on relevant spare block in said defect management information. The rewritable optical disc for realizing said method is also disclosed.

Description

【Technical field】 [0001] The present invention relates to a rewritable optical disc and a management method for the defective storage module of the optical disc. Specifically, when the defective storage module of the optical disc is replaced and stored, the information of whether there is a sector that can be replaced and stored normally in the sectors of the spare storage is prompted, so that the data storage and storage of the optical disc can be effectively stored. The method to manage the read action. 【Background technique】 [0002] For optical storage media, optical discs that can store a large amount of data are now commonly used. Among them, it also includes the newly developed new high-density optical storage media (HD-DVD) that can record and store high-quality video data and high-quality audio data for a long time, such as: Blu-ray Disc (Blue -ray Disc: hereinafter referred to as "BD") is one of them. [0003] For the Blu-ray Disc (BD) using the second-generatio...
